Abstract

The LED modular display system includes a frame of support members of triangular cross sections. The frame supports a plurality of LED display modules which include a generally planar front face upon which an array of LEDs is placed. The LED display modules further include inwardly tapered vertical sidewalls and horizontal upper and lower trapezoidal faces. The support members of triangular cross section fit flush against the inwardly tapered vertical sidewalls of the LED display modules. Fasteners on the inwardly tapering walls of the LED display modules engage complementary elements on the support members.

Claims

1. An LED modular display system comprising:

a frame including a plurality of support members oriented in a first direction, said support members having tapered vertical sides thereby forming a substantially triangular cross section, said support members further including first attachment elements;

a plurality of LED display modules, said LED display modules including a generally planar front face with an array of LEDs thereon, vertical sidewalls tapering inwardly from said front face, said vertical sidewalls further including second attachment elements;

wherein said tapered vertical sides of said support elements fit flush against said inwardly tapering vertical sidewalls of said LED display modules; and

wherein said first attachment elements engage said second attachment elements thereby attaching said LED display modules to said frame.

2. The LED modular display system of claim 1 wherein said plurality of LED display modules include horizontal upper walls and horizontal lower walls.

3. The LED modular display system of claim 2 wherein said plurality of LED display modules include a rear face through which electrical connections are made to said array of LEDs.

4. The LED modular display system of claim 3 wherein said horizontal upper walls and said horizontal lower walls of said plurality of LED display modules are trapezoidal.

5. The LED modular display system of claim 4 wherein a trapezoidal shape of said horizontal upper walls and said horizontal lower walls includes parallel edges formed by said front face and said rear face and two non-parallel edges formed by said inwardly tapering vertical sidewalls.

6. The LED modular display system of claim 5 wherein said first direction is vertical.
